Phenyl chlorothioformates are produced in high yields easily and safely by (1) allowing sulfur dioxide to react with a mixed solution consisting of perchloromethyl mercaptan, an organic solvent and water, (2) removing the aqueous layer from the reaction mixture and (3) adding to the organic layer a phenol compound and a dehydrohalogenating agent in that order.

Process for producing phenyl chlorothioformates

An antifungal composition comprising an effective amount of carbamate derivative having the formula (I): ##STR1## where X is 2-naphthyl, 5-indanyl, 5,6,7,8-tetrahydro-2-naphthyl, 1,4-methano-1,2,3,4-tetrahydro-6-naphthyl, 1,4-ethano-1,2,3,4-tetrahydro-6-naphthyl, 2-quinolyl, or a phenyl group having one or two of the same or different substituents selected from the group of halogen atom, lower alkyl, lower alkenyl, lower alkoxy, lower alkenyloxy, halogenated lower alkyl, lower alkylthio, lower alkylsulfonyl, lower alkylamino, nitro, and methylenedioxy;

Antifungal compositions

Isoindolinone pigments of an extremely high purity, which are represented by the following general formula: ##STR1## wherein R represents a carbocyclic bridge member such as:
